In pure scientific study about the Historical Muhammad raises basic questions concerning the prophet’s role as a moral paragon; the sources of Islamic law; and the God-given nature of the Koran. The scientists even doubt the existence of Muhammad. Scientists say that the Koran is a not a product of Muhammad or even of Arabia, but a collection of materials stitched together to meet the needs of a later age. There was no Islam until two or three hundred years after the traditional version at around 830CE. The Arab tribesmen who conquered in the seventh century vast territory were not Moslems, but were persons who worshiped idols and are scientists call them pagans.
